[xybrek]

How to inject HttpServletRequest in a Errai service implementation (server side) for use with code like this:

	@Override
	public void login(String username, String password, boolean rememberMe) {
		try {
			HttpServletRequest request = null;

            String host = request.getRemoteHost();

            UsernamePasswordToken token = new UsernamePasswordToken(username, password, rememberMe, host);

            try {

                Subject subject = SecurityUtils.getSubject();

                loginWithNewSession(token, subject);

                subject.login(token);

            } catch (AuthenticationException e) {

throw new IllegalArgumentException("Service could not authenticate caller with the given authorization credentials.");

            }

        } catch (Exception e) {

	e.printStackTrace();
	throw new IllegalArgumentException("Something went wrong with the login request");
}
	}
